Mason began his career at the Anacostia Community Museum, where he worked as a researcher and exhibit developer for the Black Mosaic exhibition. In 1994, he moved to the National Museum of Natural History to work as an exhibit developer and co-curator on the African Voices exhibit. Since that time, he has developed or curated more than 60 exhibitions, including Ritmos de Identidad/Rhythms of Identity at the Arts and Industries Building with the Smithsonian Latino Center, and Discovering Rastafari. In 2009, he became the Director of Exhibitions, where he was instrumental in the development and opening of the David H. Koch Hall of Human Origins in 2010. As one of the leaders of the Recovering Voices initiative at the Smithsonian, he has led the planning for the proposed Recovering Voices exhibition at NMNH, designed to put a human face on the global crisis of language and knowledge loss. In 2012, he led a collaboration between the Smithsonian and the NGO Cultural Survival to host the international conference, "Our Voices on the Air: Reaching New Audiences through Indigenous Radio", convening 28 radio producers from eight countries to explore the nexus of community radio and language revitalization. As director of the Center for Folklife and Cultural Heritage, Mason oversees the Smithsonian Folklife Festival on the National Mall, Smithsonian Folkways Recordings, and other cultural educational programs. Since his arrival in 2013, he has led the development of the Center's new Cultural Sustainability initiatives, which collaborate with communities to help them research, sustain, and present their most cherished cultural expressions. The Center's productions have won Grammy, Academy, Emmy and Webby awards.
